“…Generally the experiment is based on [10], we just add a sub experiment about comparison between hybrid using genetic algorithm and pure hybrid DCT-SVD. In these experiments, we use the peak signal to noise ratio (PSNR) to measure the quality of the watermarked image and the correlation coefficient to verify the existence of the watermark.…”

Abstract-Thecomparison between the hybrid watermarking using genetic algorithm and the pure hybrid DCT-SVD (Discrete Cosine Transform-Singular Value Decomposition) is presented.The watermark scheme is based on DCT-SVD]; applying DCT to the host image, map the DCT coefficient in a zigzag order, then propose the SVD on the sub-block and the singular value in each sub block that will be modified to embed the watermark image. Afterward the image quality can be improved with the GA-based evolution. Experimental results are shown the best extracted watermark quality of hybrid DCT-SVD between the hybrid using genetic algorithm and pure hybrid DCT-SVD.

“…This process is accomplished by concealing the watermark information into overt carrier data [10]. Like steganography, watermarking can be used in many different applications such as content authentication, digital fingerprints, broadcast monitoring, copyright protection, and intellectual property protection [11]. Different watermarking techniques can be found in the literature.…”

Nowadays, the science of information hiding has gained tremendous significance due to advances in information and communication technology. The performance of any steganographic algorithm relies on the embedding efficiency, embedding payload, and robustness against attackers. Low hidden ratio, less security, and low quality of stego videos are the major issues of many existing steganographic methods. In this paper, we propose a novel video steganography method in discrete cosine transform (DCT) domain based on error correcting codes (ECC). To improve the security of the proposed algorithm, a secret message is first encrypted and encoded by using Hamming and BCH codes. Then, it is embedded into the DCT coefficients of video frames. The hidden message is embedded into DCT coefficients of each Y, U, and V planes excluding DC coefficients. The proposed algorithm is tested under two types of videos that contain slow and fast moving objects. The experiential results of the proposed algorithm are compared with three existing methods. The comparison results show that our proposed algorithm outperformed other algorithms. The hidden ratio of the proposed algorithm is approximately 27.53%, which is considered as a high hiding capacity with a minimal tradeoff of the visual quality. The robustness of the proposed algorithm was tested under different attacks.

In this paper, a new chaos based watermarking scheme for effective tamper detection in images is proposed. The proposed scheme is able to detect any possible forgery and spot the areas which have been tampered. To improve the efficiency of the proposed scheme, a binary watermark is constructed from the image itself, which makes the watermark unique for every image and guarantee the blindness in the detection process. To guarantee the security of the proposed scheme, chaotic maps are used to complicate the embedding and the detection process to reduce the vulnerability to different attacks. Experimental results and security analysis show that the proposed scheme achieves superior tamper detection under common attacks.
